[Insight-developers] linker won't build new library

[Luis Ibanez]

Hi Michael,

0) You are using the test signature:

          itkArray1DToDataTest(int, char**)

     while, it should be:

          itkArray1DToDataTest(int, char* [])

     as in

   itkArray1DToDataTest(int argc, char * argv [] )


1) Are you building Shared Libraries ?

If so,


2) Did you put the EXPORT symbol in the
    declaration of the Array1DToData class ?


3) Is your code in a place where we could take a look ?



   Thanks


          Luis
